A metal-free radical oxidative decarboxylation/cyclization of acyl peroxides and 2-isocyanobiphenyls was achieved, leading to 6-aryl phenanthridines as well as 6-alkyl phenanthridines in moderate to good yields. The procedure featured simple conditions and was metal-free and base free. It represents a practical approach to access 6-aryl/alkyl phenanthridines.

6-Aryl substituted phenanthridines were synthesized via a visible-light-catalyzed cyclization of 2-isocyanobiphenyls with arylsulfonyl chlorides under oxidant-free and transition-metal-free conditions. This transformation represents an efficient and attractive synthetic utilization of arylsulfonyl chlorides. the Partner Organisations 2014.
Modular synthesis of phenanthridine derivatives by oxidative cyclization of 2-isocyanobiphenyls with organoboron reagents

Where HAS you been? A manganese-mediated annulation of 2-isocyanobiaryls with organoboronic acids is developed for the synthesis of a broad range of phenanthridine derivatives (see scheme). Mechanistic studies indicate that the reaction proceeds by the intramolecular homolytic aromatic substitution (HAS) of an imidoyl radical intermediate. Copyright
Indium(III)-catalyzed tandem reaction with alkynylbenzaldehydes and alkynylanilines to heteroaromatic compounds

(Chemical Equation Presented) Starting from ortho-alkynylbenzaldehydes and ortho-alkynylanilines, In(OTf)3-catalyzed synthesis of ring-condensed heteroaromatic compounds was developed via a domino intramolecular nucleophilic attack/intermolecular cycloaddition/dehydration reaction.
Ring Fragmentation of Benzotriazol-1-yl Carbanions
Katritzky, Alan R.,Lan, Xiangfu,Lam, Jamshed N.
, p. 1431 - 1434 (2007/10/02)
The title carbanions 1 are shown to lose nitrogen to afford ortho-carbiminophenyl anions 4 which can be protonated by inter- or intramolecular proton transfer to react inter- or intramolecularly with other types of electrophilic center.
